Bye, Bye, Charlie Sheen! Brooke Mueller’s Out Of Her Treatment Program & She’s Not Wearing Her Wedding Ring!

Charlie Sheen’s estranged wife stepped out in LA Wednesday night to pick up a replacement ring for the one that’s no longer on her finger!

Brooke Mueller has reemerged from the cocoon of her “stress-management” program (which others are calling “rehab”) to trade in her MIA wedding ring bling for a whole new slew of jewels.

Charlie Sheen’s estranged wife made an appearance at the Lia Sophia Lanaya II collection preview at West Hollywood’s Sunset Tower July 14 to pick up the new line – and put a new ring on her barren finger. And guess what, BFFs? This new ring had a diamond as well – although the oversized, $175 wrapped cuff ring she selected was a wee bit smaller than her engagement ice!

An insider tells us that Brooke, 32, kept to herself at the event, hanging out by the pool before quickly trying on the baubles. She stayed for a little under an hour and looked exhausted, as if she wanted to rush home and avoid human contact.

She and 44-year-old Charlie, who are the parents of 1-year-old sons Max and Bob, have been living apart since their Christmas day altercation; Charlie was arrested in Aspen, Colo. after a domestic dispute. His July 12 hearing for second-degree assault has been postponed, and according to Brooke’s rep, the two have not signed divorce papers – yet.
